Strawberry plant named &#39;civh725&#39;

ABSTRACT

This invention relates to a new and distinct variety of strawberry plant named ‘CIVH725’. The new june bearing strawberry variety named ‘CIVH725’ is primarily adapted to the climate and growing conditions of Northern areas and is characterized by a rustic plant, tolerant to the most common leaf and root diseases, suitable for tunnel and open field cultivation. The plant has medium-high vigour with semi-upright habit and clearly visible fruit, easy to collect; and the plant is able to have an important second flowering during the season. The new strawberry has a very high productivity, progressive and consistent during all the picking season. The fruits have conical and regular shape with red bright colour, uniform on all the fruit surface; very good resistance to handling and very good shelf-life. The flavour is very good, sweet and slightly aromatic.

Latin name of the genus and species of the plant claimed: Fragaria x ananassa Duchesne ex Rozier.

Variety denomination: ‘CIVH725’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘CIVH725’. The variety is botanically known as Fragaria x ananassa Duchesne ex Rozier.

The new strawberry ‘CIVH725’ is a product of a planned breeding program conducted by the inventor, Michelangelo Leis in San Giuseppe di Comacchio, Ferrara, Italy. The objective of the breeding program is to develop june bearing strawberry variety with high chill requirement, suitable both for tunnel and open field cultivation; plant with medium vigour and semi-upright habit in order to have clearly fruit easy to collect; fruit with conical, regular shape and bright red colour; skin of the fruits very resistant to handling adapted to long shelf life.

This new strawberry ‘CIVH725’ is a result of a controlled cross made by the inventor in 2011, in San Giuseppe di Comacchio, Ferrara, Italy. The male or pollen parent is strawberry selection designated 6C9C-007 (unpatented CIV's selection). The female or seed parent is strawberry selection designated Z6T2-060 (unpatented CIV's selection).

The new strawberry ‘CIVH725’ was discovered and selected by the inventor as a single flowering plant within the progeny of the stated cross in May 2013 in San Giuseppe di Comacchio, Ferrara, Italy (44°45′ North and 12°11′ East). After its selection, the new variety was asexually propagated by stolons in a nursery located in San Giuseppe di Comacchio, Ferrara, Italy. The new variety was extensively tested over the next several years in different European area with high chill condition. This propagation has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF SUMMARY OF THE INVENTION

‘CIVH725’ is primarily adapted to the climate and growing with high chill condition. This area provides the needed and correct temperatures for flower induction, and to produce a strong and vigorous plant, and to maintain fruit quality during full production.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘CIVH725’, which in combination distinguish this strawberry plant as a new and distinct variety:

-   -   1. Plants with semi-upright habit and medium-high vigour.     -   2. Adapt for tunnel and open field cultivation.     -   3. Fruits easy to collect.     -   4. Fruit with conical and regular shape during all the picking         season.     -   5. Very good resistance to handling.     -   6. Good shelf life.     -   7. Very high productivity, progressive and consistent during all         the picking season.     -   8. Important second flowering after the first production peak.

Plants of the new strawberry variety ‘CIVH725’ differ from plants of the parents, 6C9C-007 and Z6T2-060 in the characteristics described in Table 1.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new strawberry variety ‘CIVH725’ is the strawberry variety APRICA. Plants of the new strawberry variety ‘CIVH725’ differ from plants of strawberry variety APRICA in the characteristics described in Table 2:

BRIEF DESCRIPTIONS OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of typical specimens of the new strawberry variety ‘CIVH725’, at various stages of development as true as it is reasonably possible with color reproductions of this type. Color in the photographs may differ slightly from the color value cited in the botanical description which accurately describe the color of ‘CIVH725’. The depicted plant and plant parts of the new strawberry variety ‘CIVH725’ were taken in San Giuseppe di Comacchio, Ferrara, Italy, and are approximately 6 to 9 months old.

DETAILED BOTANICAL DESCRIPTION

‘CIVH725’ has not been observed under all possible environmental conditions. The characteristics of the new variety may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location.

The aforementioned photographs, together with the following observations, measurements and values describe the new strawberry variety ‘CIVH725’, unless otherwise noted, taken during 2022 growing season in San Giuseppe di Comacchio, Ferrara, Italy. The observations, measurements and values were taken from plants of ‘CIVH725’ dug in December 2020 from CIV' nursery located in 44021 Codigoro, Ferrara, (locality Pomposa), Italy, and planted in July 2021 in CIV' test field in San Giuseppe di Comacchio, Ferrara, Italy.

Plants of the new strawberry variety ‘CIVH725’ were grown under conditions which closely approximate those generally used in commercial practice.

The observed plants were one year old plants. The plants used in the production field are produced in a nursery in CIV' nursery located in 44021 Codigoro, Ferrara, (locality Pomposa), Italy.

Yield observations and fruit quality characteristics are averaged from 3 year of data collected from the 2020 through 2022 growing seasons. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit unless otherwise noted.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used. Color values were taken under daylight conditions approximately in the afternoon in San Giuseppe di Comacchio, Ferrara, Italy. The approximate age of the observed plants is about 12 months.
